VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 226,816, dated April 20, 1880.

Application filed December 1, 1879.

To all whom it may concern:

Be it known that I, JOSEPH S. Woon, of the city of Brooklyn, in the county of Kings and State of New York, have invented certain new 5 and useful Improvements in Vapor-Burners,

of which the following is a specification.

This invention has reference to that class of vapor-burners in which acurved spreader-plate is used, by which the burner-tube is heated, so

that the oil is changed into vapors, which, on

being mixed with atmospheric air, form an illuminating-gas that burns without smoking.

The invention consists of a vapor-burner provided with a vaporizing-chamber and needlevalve, and with a spreader-plate, which is connected by a horizontal portion, parallel to the needle-valve, to the vaporizing-chamber, said spreader-plate having an offset or shoulder between the horizontal portion and its wider end portion. The offset or shoulder has an air-port in line with the needle-valve, and an air-supply orifice or orifices, which pass transversely to the air-port through the offset.

In the accompanying drawings, which illus- 2 5 trate my invention, Figure 1 represents a top view; and Fig.2, avertical longitudinal section of the same on line 00 00, Fig. 1.

Similar letters of reference indicate corresponding parts.

0 A in the drawings represents a spreaderplate, which is attached by an upper horizontal portion, A, to the burner-tube B. The oil is supplied to the burner-tube from the reservoir at a suitable pressure, and the burner 3 5 lighted, in the customary manner, by igniting alcohol or oil in acup (not shown in the drawings) surrounding the burner-tube. The oil is changed by the heat of the alcohol-flame into vapors, the latter escaping at a considerable 4o pressure to the outside of the burner-tube through an outlet-orifice, a. The vapor outlet or orifice a is closed by a valve-cock, O, the conically-tapering end b of which is accurately fitted into the tapering outlet of the burner- 5 tube. The valve-ste1n is threaded and adjusted in an interiorly-threaded supporting-sleeve, O, of the burner-tube.

The spreader-plate A is provided with an angular portion or offset, d, which extends 5o downward from the upper portion, A, the

spreader-plate proper extending sidewise from the lower part of the offset. The spreaderplate is gradually curved upward and inward, and its width increased, so as to be widest at the outer end. In the offset 01 is arranged an air-port, e, in line with the vapor-orifice and valve-stem. The vapor-orifice is placed, preferably, either close to or almost inside of the air-port, to throw the jet of vapors through the same onto the upper side of the spreader-plate. In its passage through the air-port the vapor mingles with atmospheric air, which is drawn in through an air-hole, e, that passes from the air-port e downward, and also through a second orifice, 0 that extends from the air-port upward to the top of plate A. The intermingled vapors and air impinge against the curved portion of the spreader-plate and are burned at the edge of the same.

The operation of the burner is as follows: After the alcohol or oil in the heating-cup is lighted and the burner-tube heated properly thereby, the vapor passes through the vapororifice, through the air-port, and takes up, in its passage through the same, the required quantity of air through the air-supply holes. The illuminating-gas formed by this mixture is lighted, the flame appearing at the edge of the spreader-plate. The heat of the spreaderplate keeps the burner-tube in a heated state, so that the generation of vapor therein is continued, and thus a constant supply of gas furnished to the spreader-plate. The vapor, inits passage through the air-port, is mixed with the proper quantity of air necessary for combustion, and burns with a clear flame and without smoke.

I am aware that a spreader-plate connected with the vaporizing-chamber and adapted to receive the current of combined air and gas, 0 which spreader-plate also serves to heat the vaporizing-chamber, is well known and has been used heretofore; but this spreader-plate required a separate air and gas directing device above the spreader-plate proper, which I 5 wholly dispense .with by the arrangement of an offset or shoulder with an air-port in one piece with the spreader-plate and extension, which shoulder is the essential feature of this invention. 10o

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent In vapor-burners provided with a vaporizin gchamber and a needle-valve adapted to regulate the flow of gas from said chamber, the combination, with said vaporizing-chamber and needlevalve, of a spreadenplate having a horizontal portion parallel to the needle-valve by which the spreader-plate is connected to the vaporizing-chamber, and an offset or shoulder between the spreader-plate and horizontal portion said offset having an air-port in line with the valve-orifice and needle-valve, and an airsupply orifice or orifices passing transversely thereto through the ofl'set, substantially as set 15 forth.

In testimony that I claim the foregoing as my invention I have signed my name, inpresence of two Witnesses, this 8th day of November, 1879.
